Stuxnet: Could Cyber Superweapon Be Turned on U.S.?

According to the Congressional report, "It is widely believe that terrorist organizations do not currently posses the capability or have [not] made the necessary arrangements with technically savvy organizations to develop a Stuxnet-type worm. However... Stuxnet's design revelations may make it easier for terrorist organizations to develop such capabilities in the future."

That would not be such a problem, Clarke said, "except for the fact that the thousands of computer networks that run our economy are essentially defenseless against sophisticated computer attacks."

"One can be sure that highly skilled hackers in several countries are even now taking it apart, modifying it and getting it ready to destroy some other target," Clarke wrote in a analysis of the Stuxnet threat for ABC News. "They are benefiting from free access to the most sophisticated computer attack weapon ever created."
